APPARATUS FOR PRESERVING FOOD.

SPECIFICATION forming part of Letters Patent N0. 427,822, dated May 13,1890.

I Application filed September 16, 1889. Serial No. 324,058. (No model.)

.To all whom it may concern,.-

Be it known that I, JosIAH BURNHAM AN- DERsON, of Boston, in the countyof Suffolk and State of Massachusetts, have invented 5 certain new anduseful Improvements in the Method of and Apparatus for Preserving Foodand other Articles, of which the following is a speciiication. l

The object of my invention is to provide a 1o novel method of andapparatus for preserving food and other articles; and it consists in aseries of independent and separate apartments or compartments connectedtogether in a case so as to form a species of a refriger- I5 ator, buteach of. which compartments is independent and air-tight of the otherand has its independent pipe for exhausting' the air, and furtherconstructed and arranged as hereinafter described and claimed.

zo In the accompanying drawings, Figure l illustrates a front elevationof my improved preserving apparatus or refrigerator with one of theoutside doors and one of the compartment-doors open. Fig. 2 is atransverse ver- 2 5 tical section through the compartments.

Similar letters represent like parts in both of the figures.

A is an outer casing, having the doors B B and C C. The upper portion ofsaid casing 3o A incloses the air-tight compartments D, each of which isindependent of and disconnected from the others, said compartments beingpreferably separated from eachother by the ordinary metal walls andfilling now used 3 5 in refrigerators. Each compartment D is providedwith an air-tight door E, and also each compartment has an air-tube aenter-y ing the same through its doorB, said tube being connected Withan air-pump for exhaust- 1o ing the air from the compartment. I haveshown in the drawings the air-tubes ce as passing through the doorsE;but said tubes may,

if desired, enter the compartments D in any other manner-as, forexample, through the Walls. 45

I have shown in the drawings a very sim- -ple form of air-pump, the tubea forming the casing or cylinder for the same, and 111e piston-rod bhaving the handle c at its other end for operating said piston. Thecourse of the 5o exhaust-air is indicated by the arrowsin Fig. 2.

A separate compartment F in the bottom of the casing A may be used forice; but this compartment is entirely disconnected and separated fromthe compartments D, and is 5 5 not an important feature of Inyinvention.

By my invention the necessity of using ice and the trouble and expenseincurred thereby are avoided, and the exhaust-tube and airpumpattachments-such as above described, 6o and shown in the drawingsarevery simple and inexpensive.

Vhat I claim as my invent-ion, and desire to secure by LettersPatent,is-

An improved apparatus for preserving food 65 and other articles,consisting of a case provided with a series of compartments entirelyinclosed in said case and separated from each other by partitions, eachindependent compartment provided with an air-tight lining 7o and eachhaving an independent tube entering the same, and an ai r-pump connectedwith each of said tubes, whereby each compartment maybe independentlyexhausted of air or its readmission thereto prevented, snbstan- 75tially as described.

In testimony whereof I have signed my name to this specificatiomin thepresence of two subscribing witnesses, this 12th day of September, A. D.1889.
